A spokesman for Marks & Spencer said: “We’re working closely with our partner DHL on the future of the site.

“The proposal is not a reflection of the site’s performance or its employees, it has been made as part of our long-term supply chain transformation programme to deliver a more efficient M&S.

“We understand that it will be an unsettling time for those involved and we will do all we can to support.”

Unite leaders in Coventry have also offered their support to any union members at the Baginton warehouse – although they say none have been in touch so far.

Alan Lewis of Unite said: “It doesn’t look as though we have any members at that DHL site, however, if it turns out that we do, Unite will do all it can to help and support them through this difficult time.

“If any workers at this DHL site lose their jobs, then they should be given the opportunity to apply to work on other contracts that DHL operates.

“That would give them access to around half a dozen sites across the Coventry area.

“This news is a further blow for the region and all job losses are regrettable.”

“On a wider note, we don’t believe it points to a changing trend in the economy. There is still confidence among businesses across Coventry and Warwickshire and unemployment has fallen strongly over recent months.

“Anyone affected can certainly speak to the Chamber of Commerce if they are thinking of establishing their own business rather than seeking new employment elsewhere, as we have start-up advisers who can help in this area.”
